Subject: [PATCH] digraphs: mark new vim entries by comparing to v7.4 copy
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Vim version 8.0 introduced «.,» so save the old output to be able to
distinguish such new features, as a lot of users are unlikely to upgrade
for a while yet.
